, Application filed January 6, 1914. Serial No. 810.573.

To all whom it may @cheer/LY' Be it known that I, CLARENCE'J. LAusoN,

.a citizen of the United States, residing at "Yonkers,'in the county of lVestchester and State of New York, have invented certain neiv and useful Improvements in Bottle- Sealing Machines, oit which the following is a specification.y

My invention relates to improvements in machines for applying closures to bottles and my objects are the production of-a continuonsly operatingr machine of simple and solid construction in which the parts Will be easily accessible for adjustment and repair and on which a maximum output will be possible with a minimum of labor.

The drawing is a vertical sectional View .of the machine.

Above the driven ,e'ear 8 and secured tov the sleeve l is the bottle support 9 provided with a plurality of bottle pads 10 on which the bottles rests.

The upper part ot' the sleeve 4 rests on the nut 6 which4 engages the thread 5 and is slidahle 'vertically lon the lower sleeve .4; by turning the nut G in adjusting for height. A- key and keyuiay 'Y prevents rotation of the upper part 'df the sleeve on the lower part and keeps the sealing.,r heads centered over the bottle pads. This upper sleeve 4 has a plurality of arms l1, equal in number to the bottlexpads 10, provided 'with guides in which sealing heads' 12 reciprocate.

The stationary shaft' 3 has a cam ring 13 With a spiral cam groove l-lcut in Yits face and is fixed to the sha-Et by a lvey and. keyway 15 so that the cam ring cannotjvrotate hut can slide up and down on the shaft as the-upper part of the sleeve is raised and lowered. The sealing '.l1eads, which may he of, any desired type, engage the groove of the cam` through rollers and studs 16.

A hopper 17 on the upper part of the machine receives a mass of closures and supplies them to a chute i8 which extends to the throats of the sealingr heads as they pass by in their rotation to deliver caps thereto.

The machine having 1eeen adjusted to the height of the bottles to he sealed and havingr a mass` of caps in the hopper is started.4 T he gears 2 and 8 in the base rotate the sleeve 4, 4 thereby rotating the bottle support 9 and sealing heads 12 and as each head passes the chute 18 it receives a closure. During the rotation the heads 12 rise and fall due to their engagement With the groove 14 in the stationary lcam ring 13 which positively reciprocates them. nsealed bottles are now fed to the machine, being placed on the bottle pads at the front a (the high side of the cam and raised posi tion of the sealing heads). As the bottle supports and heads rotate the heads are gradually pushed Adown by the cam groove until at the rear of the machine b (or low side of the cam Iroove and bottom position of the heads) the closure is afliXed to the mouth o'l the bottle hermetically sealing it. Continued rotation raises the head ready to repeat the cycle of operations.

Bv reciprocating the sealing' heads instead of the bottles and continuously rotatiner the bottle support in a plane all agita tion of the liquids and rockingr of the bottl es is prevented.

As all the principal workingr parts are of simple and sturdy construction and are located on the outside of the machine they are easily 'accessible for adjustment and repair.

I claim:- 1. In a bottle sealing machine the combination of a plurality of bottle supports and an equal number ot' sealing heads slidably mounted thereover in alinementthereWit-h, thel supports and heads rotating together, a stationary cam ring the cam portion of which engages the heads for positively rais= in gr and lowering them, and means for supplying the sealing' heads with closures during,Y rotation.

In a bottle sealing machine, the combination of a hase.` a fixedvertical shaft tlwretln'ough, a sleeve surrounding the shaft. drivingmeans engaging the sleeve to rotate it, a plurality ot' bottle supports on the lsleeve, an equal number of sealing heads slidably mounted on the sleeve above the hottie supports, the supports and hea'ds rotating' together in alineme'nt, e. cemring; secured to the shaft, the earn portion oi. which engages the 'sealing heads. forpositively raising and lowering them.

3. In a bottle sealing machine the combinntion`0f a base, e 'liXed vertical shaft therethrough, a sleeve surrounding the shut@ the upper part of which is adjustable with respeet vto the lower part, a plurality of bottle supports on the lower part of the sleeve, an equal number of sealing heads sldebly mounted on the upper part of the sleeve in alnement with the bottle supports, e cem .ring secured to the shaft the @am portion of meuse@ bottle supports, a cam ring vertically slid,-

able, but non-rotatable, on the' shaft the eem portion of which engages the sealing heads 'for positively raising and lowering them,

means fork supplying the heads with vkcaps and means for rotating the sleeve v and attachedperts. l ln testimony whereof I have alxed my signature in preeence of .two witnesses.
